Referring more particularly to the disclosure In order to rapidly propel or shoot the blade in the drawing, the novel closure and shearing or shearing element it] across the spout or stadevice I is shown as mounted upon a container tionary shearing member in tight shearing re- 2 and removably secured thereto as by threads lation therewith, the rear end I2 of the blade 3 on the interior of the device and complemenis bent upwardly to form a trigger portion and tary threads (not shown) on the exterior of the is provided with a slot 68 for receiving a lug or upneck of the bottle. 1 ward projection M on lever l5 pivotally mounted The top 4 of the device is flat and is provided upon a pin l6 spanning a bifur t d bracket with raised portion 5 substantially midway beor extension I! of the closure.

To this bracket is To insure that the liquid flows as freely as detachably secured a handle 24.

possible through the discharge spout, the closure is provided with an opening or vent 25. Since it is extremely important that the vent be opened and maintained open during pouring, I provide a pointed or tapered projection 26 formed or provided on lever l5 and aligned With the vent 25 so as to enter the latter when the trigger is released. This projection insures against clogging of the vent of any obstruction or film of the liquid which would tend to collect therein and clog the opening.

In the operation of the device, downward pressure applied to the trigger portion M of the blade ll] retracts the resilient blade against the compression of the spring 2| through the lever 15. This spring being quite heavy and tending at all times to move the blade into its closed or shearing position, it will be evident that removal of the pressure from the trigger will permit the heavy spring to propel or shoot the blade or slidable shearing member onto and across the spout, shearing and hurling the last vestige of the liquid away from the spout.

By the present arrangement of the blade, guideway lugs and position of the upper surface of the spout, the resilient outer end of the blade or slidable shearingv member will be flexed by the lugs and maintained in close contact with the upper surface of the spout and stationary shearing edge, so as to insure a clean cut-off or shearing of the dispensed liquid, and by extending the end of the blade or shearing member l0 beyond the outer edge of the spout, the last trace of the discharged liquid will be forcibly projected or hurled away from the spout. For the purpose of cleaning the blade and the top portion of the projection 5 on which the blade slides, the blade is made readily removable from the lever l5 by lifting the rear end of the blade so that it is free of the lug l4 and permits removal of the blade by withdrawing it rearwardly. It is apparent that it may be difficult to remove sticky or other substances from beneath the blade were the blade not removable. In order to prevent accidental separation of the blade from the lever it is made sufficiently flexible so that it will ride with the lever in the arc of travel of the lever, as shown in dotted lines in Figure 1.

Having disclosed my invention, I claim:

A combined shearing device and closure adapted for mounting on a container to dispense the liquid contents thereof, a dispensing spout having an arcuate stationary drip shearing edge, a resilient, slidably mounted drip cutting blade adapted to slide directly across said edge to open and close said spout and shear the liquid therefrom, the rear portion of the blade extending rearwardly of the device and being raised to provide an operating trigger, a slot in said blade, and a spring pressed lever having a portion projecting through said slot, said blade being sufficiently flexible to follow the arc of travel of the lever as and for the purpose set forth.
